How was the storm in the East Sea formed?

Tropical storms form in large seas with warm temperatures. Around the world there are three suitable areas including the South China Sea, the Bay of Bengal and the Gulf of Mexico.

A tropical storm is energized by steam rising from the ocean surface, which creates cloud and rain shapes that often accompany storms. Therefore, the presence of a large body of water (ocean, ocean) is an important condition.

The South China Sea, the Bay of Bengal and the Gulf of Mexico are all in the tropics, meeting the conditions to help the storm form, especially the surface temperature of warm seawater.

Within the tropical range, storms are often observed between the 10-30 parallel, not too close to the equator. The reason is because near the equator, Force Coriolis helps the storms move very weakly.

In addition, tropical storms often form near the Convergence Convergence Zone (ITCZ), which is the convergence of two northeast and southeast trade winds. ITCZ is an important component because it activates the movement of low air flow, eventually developing into a storm.

"Most tropical storms form from low pressure areas, swirl high and separate from a large low pressure range called the monsoon trough. This pattern is different from the Atlantic storm, which is from West African tropical waves " - explained meteorologist Dan Kottlowski of AccuWeather.com.

happens all year round in the North Sea. However, the "hurricane season" - the most frequent period of storms in the South China Sea - usually starts at the transition of the fall (October) to the first half of the northeast monsoon season (November-December).

Storms that occur during the southwest monsoon (March - September) often form east of Luzon island of the Philippines. Initially they moved toward Taiwan, and then bent in the northeast to Japan. These storms indirectly affect the South China Sea, causing high waves and strong winds.

But gradually towards the end of the year, from October to December, tropical storms mainly moved westward, crossing the Philippines and entering the South China Sea. At the end of the season, these storms tend to form deeper into the south.

How is the storm in the East Sea and Pacific Ocean named?

The storms in the East and Pacific Sea are named by the Japan Meteorological Agency based on the database of the World Meteorological Organization's Tropical Storm Program.

This list includes 140 names submitted by regional countries such as China, Japan, Vietnam, Cambodia .

The Philippines also contributes its own name, however, the Philippine Meteorological, Astronomical and Astronomical Services Agency (PAGASA) will use its local name whenever a storm enters its Responsible Area (PAR).

For example, when Typhoon Neoguri formed in early July 2014, it was known as Florita when traveling through the Philippines.

"Forecasting experts have a list of specific names to set for the storms. Periodically, a name will be drawn and replaced by another name," AccuWeather site meteorologist Jim Andrews .com explained.
